IMPROVEMENT iN ROLLERS FOR COTTON-GINS.

Specil'ieaton forming part of Letters Patent No. 46,695, dated January 3, 1865.

.To all whom it may concern:

Beit known that I, ISRAEL F. BROWN, of New London, in the county of New London and State of Connecticut, haveinyented anew and useful Improvement in Rollers for Cotton- Gins; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had. to the accompanying drawings, forming. a part of this specification, in which- Figure lis a sectional View of a roller, illustrating a mode of carrying out my invention. Fig. 2 is an outside View of the roller as ready for use, part of the covering being removed to show the body of the roller.

Similar letters of reference indicate like parts.

The use of roller-gins is niostlyconined to that class of cotton which has a long staple, and which can be peeled oit from the seed without tearing the fiber. One of the defects in the operation of this kind of gin has been that when a bunch or wad ot' cotton, whether tangled by p rcssure or compacted by moisture, presents itself to the roller and begins to be drawn through between it and the breastplate the wad causes the breast-plate to spring away from the facev of the roller in order to open for itself a passage through the gin'7 thereby permanently bending the plate and subjecting it to injury by means ofthe stripper, thus making it incapable ot' doing good work until it is repaired. In order to get rid of this di'lieultyin working the roller-gin, I have invented a new and useful method otl making the roller whereby l1 am also enabled todo more work in a given time and in a better manner than can be done by any roller-gin known or in use.

A is the shaft, and C the foundation of the roller, having a pulley turned on one of its ends, as shown.

D is the leather or other covering, which is Vwrapped a-round the body of the roller in a ample of my roller in which the elastic surface is made by putting rubber rings B upon the roller and iitting and securing them-in grooves, as shown. I accomplish the same result by securing only segments of elastic material upon the roller, either in regular or alternate order or in a continuous or in an interrupted spiral course or courses. My experiments with some specimens of cotton have led meto preferthe method shown in the drawings.

The operation ot' my roller is as follows: A wad of cotton being presented to the gin it will be drawn in by the roller, and the spiral direction ofthe path it is made to take brings it quickly opposite to the yielding surface of the roller, when it is carried through the gin without injuring any of its parts.

l-Iaving thus described my invention, I claim as new and desire to secure by Letters Patentl. Making the drawing-in or working roller of a roller cotton-gin with a surface partly solid and part-1y elastic, substantially as described. i l

2. Putting elastic bands or rings around the roller of a roller-gin in parallel and in continuous or in interrupted lines, substantially as described.
